Please answer this question below with all work shown. A 2kg block is placed at rest on a frictionless incline that is angled 25o. It is released and slides 30.0 cm (distance s) along the incline before reaching the floor. The floor exerts a kinetic friction force f of 1 N on the block. How far does the block slide (distance x) on the flat section (different from s) before it stops?

7.7. Please answer all the
questions and show your work.
A 4.20-kg block is set into motion up an inclined plane with an initial speed of v_1 = 7.60 m/s (see figure below). The block comes to rest after traveling d = 3.00 m along the plane, which is inclined at an angle of theta = 30.0 degree to the horizontal. For this motion, determine the change in the block's kinetic energy. J For this motion, determine the change in...

Please show all work for a high rated answer.
Two blocks are attached to one another, as shown, by means of a massless cord that passes over a massless frictionless pulley. Block 1 (mass m1, = 10.0 kg) is connected to a spring with spring constant k = 100 N/m, and block 2 (mass m2 = 20.0 kg) sits on a frictionless ramp that makes an angle theta = 30.0 degree with the horizontal. The coefficient of kinetic friction between...
